"MACHIN FOR MAK-ING ROLLED FORGINGS.

SPECIFICATION forming partl of Letters yPatent No. 412,383, dated October 8, 1,889.

Application sled August 14,1889. sgml No. 320,725. (No moda.)

To all whom it may concern:

Be it known that I, CHARLES E. GoULD, of Leominster,in the county of Worcester, State of Massachusetts, have invented a certain new anduseful Improvement in Machines for Making Rolled Forgings, of which the vfollowing is a description sufficiently full, clear, and exact to enable any person skilledv in the art or science to which said invention appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- A Figure l is a side elevation of myimproved machine; Fig. 2, a sectional elevation taken on the line a :r in Fig. 1; Fig. 3, alike view on the line y y in Fig. 1, and'Fig. 4 an enlarged sectional view showing the formation of the working-face of the dies.

Like letters and figures vofl reference indicate corresponding parts in the different fige ures of the drawings.

My invention relates to that. classof machines for making rolled forgings in which one forming-die moves over or past the other while in contact with the bar being acted upon; and it consists in certain novelfeatures, as hereinafter ltully set forth 'and claimed, the object being to produce a simpler, cheaper, and more effective device of this character than is now in ordinary-use.

f vlhenature and operation of the improvementfwillbe readily understood by all conversant with such matters from the following explanation j yIn the drawings, kA represents the bench or frame-work of the machine, which consists of a bed-piece b, supported by standards or legs d, connected by braces f.- The bed or table b is provided in its upper face with twoV longitudinally-arranged V -shaped tracks or grooves g and centrally with a rectangular groove or track h. A platen B is provided on its under face with'rtwo V-shaped iianges fi, iitted to work inthe tracks g, and centrally with a cross-sectional rectangular flange j, working in the track h. The lower edge of the v:iiange j isr toothed at Za, forming a rack.

' "jAhorizontal rotating shaft Z is journaled in the bench A and a standard m, said shaft bearing fast and loose pulleys p q, whereby a reciprocating movement may be imparted by means of a crossed and straight belt and shipper in the ordinary manner.

A horizontal rotating shaft r is j centrally in the table b and bears a gear tat its outer end, meshing with a pinion u on the shaft Z. A centrally-arranged pinion w on the shaft o" meshes with the rack j on the platen B.' A stub-shaftl is journaled in a block. 16, secured centrallyT to the rear edge of the table b, said shaft bearing a pinion 17, meshing with a longitudinally-arranged rack 18, at the rear edge of the platen B. A shaft 19 is journaled in standards 2O and 21, se-

cured centrally at the front and rear edges of the table, said shaft bearing a large gear 22, which meshes with the pinion 17. The bearing of the shaft 19 in the standard 21 is cushioned on a spring 23 and is adjustable vertically by means of a set-screw 24, which passes through the top of said standard.

1 A horizontal die C is secured to the face of the platenv B, and consists of a bed-piece 25, provided with a vertically-inclined Workingface 26. flanges or bosses 27, the outer edges of which incline outwardly (see Fig. 4) at 28 and diverge gradually from the lower end 29 of said face to its highest end 30. The face between the bosses 27 is groved longitudinally at 31 to conform to the shape of the article to be rolled, (see Fig. 4,) said article being in the present instance a tool-handle.

A broad wheel 32 is secured to the shaft 19 and bears a die D, consisting of a curved bed-plate 33, provided with a Working-face 35, constructed in the same form and of the same size as the die (C, said die D being, however, as shown, convex in longitudinal section. The dies are disposed in the same vertical plane,'with their cutting-bosses 27 and 36 registering with the ends 29 and 30 of the die C, being disposed diametrically opposite the corresponding ends 37 and 38Y of the die D, and their working-faces being of the same length;

In the use of my improvement the shaft Z, being set in motion, rotates the shaft fr and drives the platen B horizontally in the tracks g. As the platen moves, the rack 18 rotates The face 26 comprises two cutting o'urnaled IOO the shaft 19 and causes the die-Wheel 32 to revolve in a direction opposite to that in which the platen moves. A bar H, from which lthe forging is to be rolled after being properly heated, is passed through an opening 40 in the standard 21, which serves as a guide therefor, and laterally between the dies C D as their ends 29 and 37 of their respective working-faces approach each other. The cutting-bosses of the dies engage said bar on opposite sides, and as they pass each other form the handle 50, or other article to which the dies are adapted, in a manner readily understood by all conversant with such matters. The bar is rotated by the action of the dies as they pass. By indenting or corrugating the beveled faces 28 of the bosses this rotation is made more regular, and the article thus formed is more perfect in shape. The bosses bisect the bar at each end of the forging, a waste piece 51 falling onto the platen, from which it may be readily removed. One end of the shaft 19, resting on the spring 23, depresses it slightly When not in action, thus aording sucient play to easily insert the bar. The reciprocating movement completes the formation of the article much more perfectly than when the Wheel completely revolves and avoids the necessity of directing the bar for the subsequent movements of the dies.

Having thus explained my invention, what I claim is 1. In a machine for making rolled forgings, companion forming-dies having, respectively, a horizontal and rotary movement, subst-antiallyas described.
